In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

FIG. 1 is a schematic diagram of a working environment of a mobile terminal wireless local area network scanning method in an embodiment. The working environment involves various application scenarios, for example, including Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS), Long Term Evolution (Long Term Evolution, LTE), Global System for Mobile Communication (Global System for Mobile Communication, GSM) and WLAN, etc. . As a non-limiting example, the following description refers to a WLAN communication system, but such teachings are equally applicable to other types of systems. As shown in FIG. 1 , its working environment involves a mobile terminal 100, a cloud server 101, a base station 102, and a wireless access device (for example, a wireless access point Access Point, AP) 103, and the mobile terminal 100 and the base station 102 can communicate with each other. , each base station 102 can communicate with the cloud server 101, the mobile terminal 100 can also communicate with the cloud server 101 through a related network other than the base station 102, and the mobile terminal 100 can also communicate with the wireless access device 103 to establish a wireless network connect. Further, in a wireless communication system, the base station 102 receives a reverse link signal from the mobile terminal 100 . Mobile terminal 100 typically engages in calls, messaging, and other types of communications. The base station 102 processes each received reverse link signal and sends the processed signal to the mobile terminal 100 in the form of a forward link signal. Optionally, the communication channel division methods used in the above communication process include but are not limited to frequency division multiple access (frequency division multiple access, FDMA), time division multiple access (time division multiple access, TDMA) and code division multiple access (code division multiple access , CDMA).

As shown in Figure 2, in one embodiment, a wireless local area network scanning method of a mobile terminal is provided, which is applied to a terminal with a mobile communication function. The mobile terminal 100 in the working environment is used as an example for illustration. The control method of the wireless local area network switch specifically includes the following steps:

Step 202: Obtain network information of target wireless access devices capable of providing communication services for the mobile terminal in sequence according to the mobile terminal's movement trajectory, and form a current network trajectory table.

In order to connect the mobile terminal to the wireless local area network, the mobile terminal will scan to find out whether there is an available wireless local area network nearby. During the scanning process, the mobile terminal will scan all wireless access points that can currently provide communication services for the mobile terminal Device network information. The network information includes the signal strength information of the wireless local area network of the wireless access device received by the current mobile terminal, and the unique identity of each wireless access device.

Specifically, the target wireless access device is the wireless access device capable of providing the mobile terminal with the largest wireless local area network signal strength among all the wireless access devices.

Wherein, the signal strengths of the wireless local area networks corresponding to all wireless access devices received by the current mobile terminal are displayed to the user in a wireless local area network WLAN list.

When the mobile terminal is moving, it will scan in real time the wireless local area networks corresponding to all wireless access devices that can provide communication services to the mobile terminal at present, and screen out the wireless local area network with the highest signal strength among all wireless local area networks, which will have the largest signal strength The corresponding wireless access device is defined as a target wireless access device, and the identity of the target wireless access device is stored in a one-to-one correspondence with the location information of the current mobile terminal. According to the moving trajectory of the mobile terminal, the current location and the identity of the target wireless access device that the mobile terminal can scan are acquired to form a current network trajectory table.

It should be noted that the identity mark can be a user-defined name, or a model of a wireless access device, that is, the identity mark can be represented by a combination of letters, numbers, and special symbols.

It should be noted that the moving track of the mobile terminal can be obtained through GPS positioning technology, Beidou positioning technology or base station positioning technology, and the moving direction of the mobile terminal can be detected by the gyroscope installed in the mobile terminal, but the embodiment of the present application is not limited thereto , and other methods may also be used to obtain the movement track of the mobile terminal.

Step 204: calling a preset network track table, where the preset network track table is used to at least store network information of a target wireless access device corresponding to when the mobile terminal moves along the first preset track.

Wherein, the first preset track is a moving track of the mobile terminal leaving the coverage area of the wireless local area network of the available wireless access device. The preset network track table stores at least the network information of the target wireless access device corresponding to when the mobile terminal moves along the first preset track.

Specifically, the target wireless access device is the wireless access device capable of providing the mobile terminal with the largest wireless local area network signal strength among all the wireless access devices. There can be 1 or more (more than or equal to 2) moving trajectories for the mobile terminal to leave the coverage area of the wireless local area network of the available wireless access device, that is, the number of the first preset trajectories can be 1 or more (more than or equal to 2) equal to 2 bars). When there are multiple first preset tracks, a huge and orderly preset network track table can be formed according to different first preset tracks.

It should be noted that, the wireless access device can be a wireless access point AP, and the available wireless access device is a wireless local area network that the mobile terminal has successfully accessed the wireless access device, for example, an AP available for home use and an AP available for work units , Frequently visited available APs or other available APs in public areas, etc.

Further, according to the number of available wireless access devices, a preset network track table equal to the number of available wireless access devices can be formed, that is, the available wireless access devices correspond to the preset network track table one-to-one, for example, the The wireless access device corresponds to the home preset network track table, and the wireless access device available to the work unit corresponds to the work unit preset network track table.

Step 206: When the network information in the current network track table is consistent with the network information corresponding to the first preset track, activate a scan switching strategy, and switch the active scanning mode to the passive scanning mode to scan the wireless local area network.

Comparing the acquired network information of the target wireless access device corresponding to the moving track of the mobile terminal in the current network track table with the network information of the target wireless access device corresponding to the first preset track in the preset network track table. In the process of comparison, when the network information corresponding to the mobile trajectory of the mobile terminal in the current network trajectory table is consistent with the network information corresponding to the first preset trajectory in the preset network trajectory table, it indicates that the mobile terminal has left any available wireless network. The coverage area of the WLAN of the access device, such as business trips, tourism, commuting, and so on. When the mobile terminal has left the coverage area of the WLAN of any available wireless access device, start the scanning switching strategy, and switch the active scanning mode to the passive scanning mode to scan the WLAN without affecting the user experience. It can also save power consumption, improve endurance, and reduce radiation, which can avoid the use of active scanning to increase the power consumption of mobile terminals virtually, and shorten the standby time of the whole machine.

It should be noted that, for the passive scanning mode, the mobile terminal does not actively send a probe request frame, but passively receives beacon frames (Beacon) periodically sent by the wireless access point to discover the network. The beacon frame includes information such as the service set identifier of the wireless access point AP, the supported rate, the MAC address of the wireless access point, the supported authentication method, the encryption algorithm, the beacon frame transmission interval, and the channel used. For example, the default period for the wireless access point to send the beacon frame is 100ms, that is, the wireless access point broadcasts and sends the beacon frame every 100ms. The STA learns the surrounding wireless network by listening to the beacon frame on each channel it supports.

It should be noted that, for the active scanning mode, the mobile terminal will proactively send detection signals sequentially on the channels it supports to detect the surrounding wireless networks. The probe signal sent by the mobile terminal is called a probe request frame (Probe Request), and a network signal is obtained by receiving a probe response frame (Probe Response). The probe request frame can be divided into two types, one is unspecified service set identifier (Service Set Identifier, SSID), and the other is specified service set identifier. If no service set identifier is specified in the probe request frame, it means that the probe request wants to obtain all available wireless network signals around, and all wireless access points that receive the broadcast probe request frame will respond to the mobile terminal. If the SSID is specified in the probe request frame, it means that the mobile terminal only wants to find a specific SSID, and does not need other wireless networks except the specified SSID. After receiving the probe request frame, the wireless access point will respond to the mobile terminal only if it finds that the SSID in the probe request frame is the same as its own SSID.

In the above mobile terminal WLAN scanning method, when the network information corresponding to the mobile trajectory of the mobile terminal in the current network trajectory table is consistent with the network information corresponding to the first preset trajectory in the preset network trajectory table, it indicates that the mobile terminal has left Any wireless LAN coverage area where wireless access devices are available. At this time, start the scan switching strategy and switch the active scanning mode to passive scanning mode to scan the wireless LAN, which can save power consumption, improve battery life, and reduce radiation. At the same time, it will not affect the user experience.

As shown in Figure 3, in one embodiment, before calling the preset network track table, it also includes:

Step 302: When the mobile terminal leaves the coverage area of the wireless local area network of the available wireless access device, record the network information corresponding to the target wireless access device that can currently provide communication services for the mobile terminal.

The device information of the available wireless access device is obtained, including the identity of the wireless access device, the coverage area (coverage radius) of the wireless local area network of the wireless access device, and the like. When the terminal leaves the coverage area of the wireless local area network of the wireless access device, the network information corresponding to all wireless access devices capable of providing communication services for the mobile terminal is obtained through real-time scanning.

Step 304: Obtain the primary wireless access device of the available wireless access device according to the network information corresponding to all the wireless access devices.

Wherein, the network information includes the strength information of the wireless local area network corresponding to the wireless access device received by the current mobile terminal, and the identity of the wireless access device. According to the network information of all wireless access devices obtained through scanning, the target wireless access device is obtained, that is, at the moment of leaving the coverage area of the wireless LAN of the available wireless access device, the corresponding wireless LAN with the maximum signal strength is scanned The wireless access device defines the target wireless access device when it leaves the coverage area of the wireless local area network of the available wireless access device, and is also a first-class wireless access device of the available wireless access device.

The first-level wireless access device can also be understood as the wireless access device corresponding to the wireless LAN with the maximum signal strength scanned by the mobile terminal for the first time after the mobile terminal leaves the coverage area of the wireless local area network corresponding to the available wireless access device. At this time, Correspondingly record the current location information of the mobile terminal and the identity of the primary wireless access device.

Step 306: When the mobile terminal leaves the wireless local area network coverage area of the primary wireless access device, acquire the secondary wireless access device.

The secondary access device is a wireless access device capable of providing the mobile terminal with a signal of maximum strength when leaving the coverage area of the wireless local area network of the primary wireless access device.

Correspondingly, when the mobile terminal can also obtain the device information of the first-level wireless access device, the device information includes the identity of the first-level wireless access device, the wireless LAN coverage area (coverage radius) of the first-level wireless access device and many more. When the terminal leaves the wireless local area network coverage area of the first-level wireless access device, the network information corresponding to all wireless access devices that can provide communication services for the mobile terminal is obtained through real-time scanning.

According to the acquired network information of all wireless access devices, the mobile terminal can scan for the wireless LAN with the maximum signal strength at the moment when it leaves the coverage area of the wireless LAN of the first-level wireless access device, and will scan the wireless LAN with the maximum signal strength. The wireless access device corresponding to the LAN is defined as the secondary wireless access device of the available wireless access device. The secondary wireless access device can be understood as the wireless access device corresponding to the wireless LAN with the maximum signal strength scanned by the mobile terminal for the first time after the mobile terminal leaves the coverage area of the wireless LAN corresponding to the primary wireless access device. At this time, The current location information of the mobile terminal and the identity of the secondary wireless access device are correspondingly recorded.

Step 308: Define a trajectory of the mobile terminal moving from the available wireless access device to the secondary wireless access device via the primary wireless access device as the first preset movement trajectory.

Acquire the mobile terminal moving from the wireless LAN coverage area of the available wireless access device to the wireless LAN coverage area of the first-level wireless access device, and from the wireless LAN coverage area of the first-level wireless access device to the wireless network of the second-level wireless access device. A movement track of the coverage area of the local area network, and define the movement track as the first preset movement track.

It should be noted that ranges of wireless local area network coverage areas of available wireless access devices, primary wireless access devices, and secondary wireless access devices are identified on the first preset movement trajectory.

Step 310: Form the preset network track table according to the first-level wireless access device, the second-level wireless access device and the first preset movement track.

According to the obtained primary wireless access device, secondary wireless access device and the first preset movement track, a preset network track table can be formed. The preset network track table stores the mapping relationship between each location area in the first preset movement track and available wireless access devices, primary wireless access devices, and secondary wireless access devices.

Further, the formed preset network track table may be named after the identifier of the available wireless access device in step 302 .

As shown in Figure 4, in one embodiment, before calling the preset network track table, it also includes:

Step 402: Obtain orientation information of the mobile terminal leaving the coverage area of the wireless local area network of the available wireless access device and/or the coverage area of the wireless local area network of the primary wireless access device.

Specifically, when the mobile terminal leaves the coverage area of the wireless local area network corresponding to the available wireless access device, the direction of departure may be different every time. level wireless access device, that is, a new first preset trajectory can be formed.

Optionally, when the mobile terminal leaves the wireless local area network coverage area corresponding to the available wireless access device AP, if the direction of departure is the same every time, the first-level wireless access device AP_1# of the available wireless access device is the same. When leaving the location of the wireless LAN coverage area corresponding to the first-level wireless access device AP_1# is different, according to the location of leaving the wireless LAN coverage area corresponding to the first-level wireless access device AP_1#, as shown in Figure 5, you can obtain different directions. The secondary wireless access devices (AP_2#, AP_3#, . . . , AP_n#) can also form a new first preset track accordingly.

Optionally, if the direction of leaving the wireless local area network coverage area corresponding to the available wireless access device is different each time, you can correspondingly obtain the first-level wireless access device with different orientations; The location of the LAN coverage area is also different. Correspondingly, secondary wireless access devices of different locations can also be obtained correspondingly, and new wireless access devices can be formed according to available wireless access devices, primary wireless access devices, and secondary wireless access devices. The first preset track of .

Step 404: Update the preset network trajectory table according to the orientation information.

A new first preset trajectory can be formed according to the orientation information of the mobile terminal leaving the coverage area of the wireless local area network of the available wireless access device and/or the coverage area of the wireless local area network of the primary wireless access device.

According to the new first preset track and the first-level wireless access device and the second-level wireless access device obtained when forming the first preset track, a new preset network track table can be formed to implement the preset network track table updates. The preset network track table stores the mapping relationship between each location area in the first preset movement track and available wireless access devices, primary wireless access devices, and secondary wireless access devices.

In one embodiment, the preset network track table is further used to store the network information of the target wireless access device corresponding to when the mobile terminal moves along the second preset track. Wherein, the second preset track is a moving track of the mobile terminal entering the coverage area of the wireless local area network of the available wireless access device.

It should be noted that each first preset track has a corresponding second preset track. The driving distances of the correspondingly set first preset trajectory and the second preset trajectory roughly overlap to a certain extent. Meanwhile, the moving direction of the mobile terminal along the first preset track is opposite to the moving direction of the mobile terminal along the second preset track. That is, the network information of the target wireless access device corresponding to the mobile terminal moving along the first preset track stored in the preset network track table and the target wireless access device corresponding to the mobile terminal moving along the second preset track The network information of the device is set relative to each other. For example, when the mobile terminal moves according to the first preset track, the order of the wireless access devices scanned is: available wireless access devices, first-level wireless access devices, and second-level wireless access devices; The sequence of wireless access devices scanned during track movement is: secondary wireless access devices, primary wireless access devices, and available wireless access devices.

As shown in Figure 6, in one embodiment, the mobile terminal wireless local area network scanning method includes:

Step 604: call the preset network track table, which is also used to store the network information of the corresponding target wireless access device when the mobile terminal moves along the second preset track.

Step 606: When the network information in the current network track table is consistent with the network information corresponding to the second preset track, switch the passive scanning mode to the active scanning mode to scan the wireless local area network.

That is, when the mobile terminal is moving, when the network information in the current network track table is consistent with the network information corresponding to the second preset track, it can be understood that it first scans into the preset network track table Second-level wireless access devices, and then scan the first-level wireless access devices, it indicates that the mobile terminal is about to enter the wireless LAN coverage area of available wireless access devices, at this time, switch the passive scanning mode to the active scanning mode to scan It can quickly and effectively scan to an accessible wireless LAN to improve user experience.

In one embodiment, the wireless local area network scanning method for a mobile terminal further includes the step of switching the active scanning mode to a passive scanning mode when the active scanning mode is used to access the wireless local area network.

When the mobile terminal is connected to the network access device, the real-time requirements of the user to search for other network access devices are not high. At this time, switching the active scanning mode to the passive scanning mode can save power consumption and increase battery life. , while reducing radiation.
